ADDRESSING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 646,958, dated April 10, 1900..

Application filed December 31, 189 7- Serial No. 665,161. (No model.)

To all whom it may concern.-

Be it known that I, LUTHER 0. CR0 WELL, a citizen of the United-States, residing at New York, (Brooklyn,) county of Kings, and State of New York, have invented certain new and useful Improvements in AddressingMachines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to machines for printing 011 newspapers or other publications-or wrappers or other articles addresses or other matterfrom a succession of printing-surfaces.

The invention relates more particularly to the address or other consecutive printing mechanism proper.

In a construction embodying the invention in the preferred form the printing-plates are advanced successively to carry their printingsurfaces into contact with the papers or other articles to be printed by means of a reciproeating carrierby which the printing-plates are successively advanced for printing, preferably sidewise, and then released, the carrier returning for the next plate. Some features of the invention, however,'are not limited to the use of a reciprocating carrier, as will appear from the claims. The printing contact between the papers and the printing-plates preferably takes place while both are moving, the papers preferably turning about an impression-roll and the movem entof the carrier being such as to advance the plates for printing at a speed corresponding to that of the papers as they are advanced about the impression-roll. The plates are preferably arranged side by side in the holder and advanced therefrom by the carrier in the direction of their movement inthe holder,and the forward movementof the plates in the holder is preferably limited by means of a suitable stop when the plates have been advanced so as to bring the foremost plate into position to be engaged by the carrier, means being provided for releasing the foremost plate from this stop before it is advanced. for printing, preferably by moving the plate transversely to the column of plates in the holder clear of the stop, the plateengaging part of the carrierpreferably being constructed to thus move the plate clear of the stop before advancing it for printing. I

preferably employ a pivoted carrier which advances the plates for printing as it moves about its pivotal point and which also preferably oscillates to form a reciprocating carmen For the purpose of inking the printing faces of the plates before printing I preferably provide an inking-roll moving with the carrier and in contact with the printing-surfaces of the plates in the holder before they are advanced by the carrier for printing.

My improved consecutive-printing mechanism may be embodied in an independent address or other consecutiveprinting machine, suitable feeding mechanism being also preferably provided, so that the papers or other articles and the printing-plates will be advanced in proper time for causing successive plates to print on successive papers. Printing mechanism constructed in accord* ance with the invention is also especially well adapted to be combined with the folding de livery mechanism of a printing-press or with other delivery mechanism, so that the papers may be addressed as they are delivered. I have shown in the drawings a construction for so combining the address-printing mech* anism with the folding delivery mechanism which I have claimed in a prior application Serial No. 660,353.

As a full understanding of the invention can best be given by a detailed description of a preferred construction embodying all the features of the same, such a description will now be given in connection with the accompanying drawings, illustrating such a construction, and the features forming the invention will afterward be specifically pointed out in the claims.

In said drawings, Figure 1 is a view taken taken on line 4 of Fig. 6, showing the carrier and guideway through which the plates are advanced for printing. Fig. 5 is a plan View of the plate-holder and guideway. Fig. (3 is a side view of the same, partly in section, on the line 0 of Fig. 5. Fig. 7 is a detail view, partly in section, showing a printing-plate carried by the carrier in printing position. Fig. 8 is an end view, partly broken away, of the carrier.

Referring to the drawings, there is indicated in Fig. 1 by dotted lines a portion of a folding-cylinder F, having a rotary foldingblade 10 for folding the papers from the cylinder F between fold-laying rolls 11 and 12. This folding apparatus is of a type well known and shown and described in the patent to S. D. Tucker, No. 171,196, dated December 14, 1875. As the papers are advanced from the fold-laying rolls 11 12 their course is determined by a pivoted switch 13, which when in the position indicated by dotted lines in Fig. 1 directs the papers between the arm 14 of the switch and guiding-tapes 15 to and between delivery-rolls l6 and 17, from which they are guided by a vertical conductor 18 to an S-fiy X, by which they may be deposited on delivery-belts, as usual. The guidingtapes 15 run from a roll 19, near the-foldingroll 11, over the delivery-roll 1G, thence beneath the delivery-roll 17, then around atension-roll 20, and back to the roll 19. When, however, the switch is rocked to the position shown in full lines in Fig. 1, the papers will be guided to the address-printing mechanism and thence to the final-delivery rolls 16 17, as follows: Leaving the rolls 11 12, the papers are guided by the arm 21 of the switch and guiding-tapes 22 between rolls 23 and 25, then turned about the roll 25,which is the impression-roll, by the tapes 22, and advanced from the roll 25, between the tapes 22 and tapes 26 and beneath a guide 27, to the delivery-roll 16, and entered between the roll 16 and the tapes 15 to be delivered from the rolls 16 and 17 to the fiyX,as before. The tapes 22 run from the roll 28 to the roll 23, then between the rolls 23 and and around the roll 25, thence to and aroundthe roll 16 and to a roll 29, and then up to and around a tensionroll 30 and back to the roll 28. The tapes 26 turn about the roll 25 inside the tapes 22 and also about a roll 31. By the arrangement described the papers maybe delivered from the folding apparatus directly to the final-delivery apparatus or may at will, suitable means being provided for operating the switch 13, be directed to the address-printing mechanism, from which, in the machine shown,they are directed to the same final-delivery mechanism to which they may be guided directly from the folding apparatus. Such arrangement for combining an add ress-printing mechanism with a delivery mechanism is claimed in my said application, Serial No. 660,353.

The mechanism whereby the printin g-plates tact with the papers as the latter are advanced about the impression-roll 25 will now be described.

The printing-plates or are arranged side by side in a chute or holder 40, carried by a bracket 41, in which they are fed forward to bring the plates successively into position to be engaged by the carrier and advanced for printing, the holder being, preferably, inclined, as shown, so that the plates will be thus fed forward therein by gravity. The sides of the holder 40 are preferably formed with guiding-shoulders 2 and 3, by which the plates are prevented from becoming displaced as they are advanced to be taken by the carrier, and the printing-plates are preferably of the form shown, having their base portions extended at the ends, so as to enter beneath the shoulders 2 3. The forward movement of the plates in the holder is limited by means of stops 42, with which the foremost or end plate comes in contact when the plates are advanced, so as to bring the foremost plate into position to be engaged by the carrier.

The carrier is carried by a rock-shaft 46 and is provided with a plunger 47 for engaging the printing plates, which plunger is mounted to move radially of the shaft 46 and so as to project a greater or less distance. The shaft 46 is rocked for causing the carrier to oscillate by means of a pitman 48, en-

gaging a rock-arm 49 on the shaft and having its other end forked to extend over and be guided by a cam-shaft 50 and having a cam-roll which runs in a cam-groove 51 in a cam-disk 52. The shaft 46 also carries an arm 53, against which bears a spring 54, coiled about and guided by a rod pivoted to the arm 53 and having its other end guided by a collar 55 on the frame, the position of the-arm 53 circumferentially of the shaft 46 being such that the pressure of the spring 54 will tend to hold the carrier at rest when it isateitherextremity of its movement. When the carrier is in the position shown in Fig. 1, therefore, the pressure of the spring 54 on the arm 53 tends to hold it in this position.

The pitman 48 passes freely through an opening in the arm 49 and has on eitherside of said arm a collar 56 and 57, respectively adapted to bear on the arm, said collars being separated a distance greater than the thickness of the arm, so as to allow of lost motion in the connection between the pitman and the arm, and the collar '57 being, preferably, adjustable to adjust theamount of such lost motion and the movement of the plunger 47. Pivotally connected to the end of the pitman is a connecting-rod 58, the other end of which is pivoted to the plunger 47, as shown in Figs. 1 and 4. When the pitman 48 commences to move outward from the position shown in Fig. 1, therefore, there will be no movement of the carrier until the collar 57 has moved into cont-act with the arm 49; but the movement of the pitman before the collar 57 are advanced in succession for printing conengages the arm-49 will cause the plunger 47 to be projected from the end of the carrier for engaging the end printing-plate in the plateholder, as hereinafter described. Then by the further movement of the pitman after the collar 57 has come into-contact with the arm 49 the carrier will be swung about the shaft 46 to' carry the printing-plate past the impressionroll 25 for contact with a paperbeing advanced about theimpression-roll. As the pitman 48 reaches the end of its outward movement the pressure of the spring 54 on the arm 53, which has been moved so as to carry the center of its pivotal connection with the springrod to the opposite side of a line extending between the center of the shaft 46 and the collar 55 from that shown in Fig. 1,will cause the movement of the carrier to continue,and during this continued movement of the carrier the arm 49 will move on the pitman between the collars 56 and 57, so as to cause the plunger 47 to be retracted to release the plate from which the impression has just been taken. Then by the inward movement of the pitman the carrier will be caused to make its return oscillation by engagement of the collar 56 with the arm 49, and the carrier will be thus returned to the position shown in Fig. 1, further movement of the carrier under the action of the spring 53 being then prevented by a stop 59 and the plunger 47 thus held in its retracted position, as shown in said figure.

A guideway 60, formed by side guides 61, is preferably provided for guiding the plates as they are advanced by the carrier for printing, this guideway being curved in an are about the center of the shaft 46,'so as to extend concentrically. with the direction of movement of the end of thecarrier.

The printing-plates preferably have their bases formed with a recess 6 to receive the correspondingly-shaped end 70f the plunger 47 as it is projected for engaging the plate. The plunger 47 is also preferably provided with a shoulder 8 for engaging the bases of' the printing-plates, so as to provide a steadier support for the plate during printing.

The parts being in the position shown in Fig. 1, with the end printing-plate in the holder resting against the stops 42, as the plunger 47 moves outward preparatory to the oscillating movement of the carrier the end 7 of the plunger will enter the recess 6 in the end printing-plate, and as the shoulder 8 comesin contact with the base of the printing-plate the printing-plate will be raised from the position shown in Figs. 1 and 4, so as to clear the stops 42 as it is advanced for printing by the oscillation of the carrier. After printing, as the carrier reaches the end of its forward movement, the plunger 47 be ing again retracted, as before explained, and its end 7 being withdrawn from the recess 6 of the printing-plate,the plate will be released and allowed to fall through the guideway 60 to a suitable receiver. (Not shown.) After the end plate has been thus advanced from the holder the remaining plates in the holder are advanced to bring the next plate into position to be engaged by the carrier after its return to the position shown in Fig. 1 and before its next forward movement.

For inking the plates before printing I preferably provide an ink-roller 65,arranged to run in contact with the printing-surfaces of the plates as they lie in the holder and having its shaft connected by arms 66 with the carrier, so that by the oscillating movements of the carrier the inking-roll will be caused to travel forward and backward over the faces of the printing-plates in the holder. The inkingroll preferably receives ink from a fountain 67 through a fountain-101168, positioned, preferably, so as to be engaged by the inking-roll when the carrier is at the end of its return movement, as shown in Figs. 1 and 6.

The inking-roll is preferably provided with running wheels or disks 69, which run on tracks 70, formed to raise the inking-roll out of contact with the plates during a part of its movement, including that part in which it is in contact with the fountain-roll.

In order to provide for a change in. the interval between successive printing move ments of the carrier, the cam-disk 52 is preferably adjustable longitudinally on its shaft 50, and the cam-groove 51 is formed so that with the disk in different positions it will cause the carrier to make its printing movements at difierent intervals. As shown,when the cam-disk is adjusted longitudinally of its shaft to the position shown the carrier will be caused to make one complete oscillation for each revolution of the cam-disk, the cam-roll on the pitman 48 running in the part a of the cam groove during half a revolution of the cam-disk to move the carrier forward for printing and back again and the cam-roll during the next half-revolution of the cam-disk followinga concentric face 1), against which it is held by the spring 54, the cam-disk being cut away to a depth less than the depth of the cam-groove to form this concentric face. When, however, the cam-disk is moved so as to cause the cam-roll to extend into the camgroove to a greater depth than the cam-disk is cut away to form the face 6, the roll will run through the part c of the cam-groove instead of following the concentric face l), so that the carrier after making one complete oscillation while the roll runs through the part a of the cam-groove, as before,will then make another complete oscillation while the roll runs through the part 0, thus making two complete oscillations for each revolution of the cam-disk and advancing the printing-plates ing mechanism is capacitated to address successive papers fed thereto at correspondinglydiffering intervals. Thus in the machine iIO shown the folding-cylinder F may be constructed to fold at each revolution either one or two papers, as desired, between the foldlaying rolls 11 12, constructions accomplishing this result being well known in the art, and then the address-printin g mechanism may be made to operate correspondingly by merely adjusting the cam-disk 52, the cam-disk being positioned as shown, when the foldingcylinder delivers one paper to the rolls 11 12 at each revolution and being moved to cause the carrier to operate twice for each revolution of the cam-disk when the folding-cylinder delivers two papers to the rolls 11 12 at each revolution. I

The various moving parts of the machine are driven from a gear on the folding-cylinder F through anintermediate '75. The camshaft 50 carries a gear 76 and is driven by a gear 77, meshing with the intermediate 75, to make one revolution to each revolution of the folding-cylinder. The shaft of the gear 77 also carries a smaller gear 78, from which the fly X is driven through a gear 7 9 on its shaft to make one revolution to two revolutions of the folding-cylinder. The deliveryrolls 16 and -17 carry intermeshing gears 80 and are driven from a gear 81 on the fly-shaft which meshes with a gear 82 on the shaft of the roll 17. The rolls 23 and 25 carry intermeshing gears 82 and 83 and are driven from the gear 81 through intermediates 84 and 85, the gear 85 running freely on the shaft of the gears 77 and 7S and meshing with the gear 83.

It will be understood that I am not to be limited to the exact construction shown for the purpose of illustrating the invention and to which the foregoing description has been mainly confined, but that the invention includes various changes and modifications therein within the claims.

The term paper is used in the claims to include all articles for printing on which the invention may be found applicable.

By the term sidewise as applied herein to the movement of the printing-plates is meant that the plates are moved in the plane of the printing-surface of the plates and transversely to the line or lines of characters forming the printing-surface.
